收藏资源简介:
该数据集由LeRobot创建,专注于机器人学领域,特别是针对双手机器人(AgileX Piper Bimanual)的操作任务。数据集包含44个训练集,总计4820帧数据,帧率为20fps。数据特征包括机器人状态观测(如左右机械臂的关节位置和夹爪状态)、机器人动作指令、以及来自前、左、右三个视角的RGB视频观测(分辨率为480x640)。此外,还包含时间戳、帧索引、任务索引等元数据。数据集以Apache 2.0许可证发布,主要用于机器人控制与学习任务的研究。
This dataset was created by LeRobot, focusing on the field of robotics, particularly for manipulation tasks of the bimanual robot (AgileX Piper Bimanual). It contains 44 training splits, totaling 4820 frames with a frame rate of 20 fps. The data features include robot state observations (e.g., joint positions and gripper states of the left and right robotic arms), robot action commands, as well as RGB video observations from three perspectives: front, left, and right, with a resolution of 480×640. Additionally, it also includes metadata such as timestamps, frame indices, and task indices. The dataset is released under the Apache 2.0 license and is primarily intended for research on robot control and learning tasks.
